Fast Japanese system with Channel mixer

Green Blue has always been the main direction of Japanese style color, fresh and beautiful, quiet and elegant, but also popular style. We usually use Photoshop "optional color" and "level" and other tools to modulate the Japanese blues, you can get very good visual effects, but we can also through other ways to achieve a better and more broad goals, the so-called road to Rome. Here to introduce "channel mixer", intuitive understanding of "channel Mixer" is mixed RGB mode red, green, blue three channels of the tool, then how to mix channels? Color or purity or clarity? What we see on the surface is the change in color, which is actually the result of mixing the brightness of each channel in different proportions.

The principle of the channel mixer is to change the color brightness of the source channel by mixing the brightness of the color in the other channel. One thing you must understand is that the source channel in the channel mixer only borrows the brightness of the other channels, not the brightness of the other channels, so it does not change the brightness of the other channels. First you need to understand the RGB three primary colors and the principle of the channel.

RGB color mode for the color mode, physicists have found that the sun's white light contains red, orange, yellow, green, green, blue, purple 7 kinds of shade, but the most basic shade of red, green, blue. If the color of the three primary colors of red, green, blue 3 kinds of light at the same time to the same amount of purity projection to the screen, that is, to become white.

All the colors on the computer screen are made up of red, green, and blue shades, which are the smallest display units, each of which has a set of red, green, and blue pixels.

Each image is made up of channels, and the grayscale, bitmap, and indexed-mode images have only one channel. RGB mode has 3 channels, the channel is used to control the amount of light, there is no color in the channel, dark shade on the formation of shading, and reduce the amount of light, light shade on the shielding effect of light, and the increase in the amount of optical flux. Black does not pass the light, the amount of white light reaches the maximum.

In RGB color mode, the brighter The red channel the more red the image, the less green, the darker the more black, the less red, the brighter the green channel the more green the image, the less magenta, the darker the more magenta, the less green; the brighter The blue channel the more blue the image, the less yellow, the darker the more yellow, the less blue. The following example is used to analyze the principle of "channel mixer", and to realize the modulation of blue and blues of fresh day.

Next look at an example of an image that is tuned using a channel mixer.

Instance

The original color is warm, our adjustment direction is the cyan hue.

First, the channel mixer is introduced. Pull up the channel mixer.

In the Pop-up Channel Mixer dialog box, options such as preset, output channel, source channel, and constant, monochrome are distributed to adjust.

In the Pop-up Channel Mixer dialog box, options such as preset, output channel, source channel, and constant, monochrome are distributed to adjust.

Output channels can select the channels in which you want to mix one or more source channels.

When you drag any of the three primary Colors "red", "green", or "blue" sliders in the source channel, you can add and subtract the percentage of the source channel in the output channel, with a value ranging from 200 to +200. Source channel according to the different color mode of the image, the color mode is RGB when the source channel for R, G, B, CMYK color mode, the source channel for C, M, Y, K.

The bottom constant adds an opaque channel to the output channel, adds black to negative values, adds white when positive, and directly reduces or increases the color.

Check "monochrome", apply the same settings to all output channels, and create grayscale images in the color mode.

specific steps to adjust the repair

1, the image of the new "Layer 1" layer, and filled to white, "set the layer of the blending mode" for "soft light", the layer of "opacity" for "30%", at this time the screen soft light, contrast decreased. This adjustment is because the Japanese blue and blues films generally light gray, contrast small, the tone of the effect of high profile.

2, new "channel mixer" adjustment layer. When the "output channel" selects "Red", transfer "red", "green", "blue", "constant" four percent only affects the red channel, the green channel and the blue channel does not have any effect, the slider moves to the right, the red channel is brighter, the picture is redder, the green is less; the slider moves to the left, the red channel is darker, the screen becomes blue, Just like curve channel adjustment. Set "constant" to "-15%", pressure red channel, so that the screen is green, and "source channel" three-color fine-tuning, in the coordination of the preliminary green tones.

3, "Output channel" choose "Green" when the same, set the "constant" for "5%", the bright green channel, so that the screen green, reduce magenta. "Source channel" of the three-color fine-tuning plus and minus, the whole to consolidate the cyan, brighten the role of the screen.

4, the screen of the green tune established. "Output channel" to choose "Blue" is still the same, set "constant" for "10%", to highlight the blue channel, so that the screen is blue, minus yellow. "Source channel" of the three-color fine-tuning plus and minus, pressure to live in the extra yellow, so that the blue and cyan better blend together to enhance the picture fresh feeling.

5, the application of "Photo filter", "filter" Select "Heating filter", "Concentration" of "25%", Drift a little blues, so that the screen is not monotonous.

6, the final combination of layers, the application of "automatic contrast" to remove a layer of soild, elegant and gentle feeling of the Japanese blue screen present.

Channel mixer in the color palette has a clear advantage, through the good control of the channel can not only reconcile color, but also to make the color contrast, the key is to understand its principles, master the Laws of color, can be applied freely, no matter what color tonal modulation can be realized immediately.
